Annotated Bibliography On The Cloud Storage

In today’s world of instant connectivity and information at users’ fingertips, it’s vital that sensitive information is safeguarded against those who seek to do personal harm and profit from gaining access to the data. The key behind keeping information safe is the method in which it’s protected and encrypted. In order to appreciate how information is secured, users must understand the encryption concepts behind it. To do this, one must comprehend the current encryption standards, the trends and developments in encryption technology, the importance of securing data, the government’s regulations pertaining to encryption, the companies involved in research and implementation, the implications of leaked or stolen data, and a brief look into

A company allows its staffs in the same groupor department to store and share files in the cloud. By utilizing the cloud, the staffs can be completely released from the troublesome local data storage and maintenance.However, it also poses a significant risk to the confidentialityof those stored files. Specifically, the cloud serversmanaged by cloud providers are not fully trusted by userswhile the data files stored in the cloud may be sensitive andconfidential, such as business plans. To preserve dataprivacy, a basic solution is to encrypt data files, and thenupload the encrypted data into the cloud. Unfortunately,designing an efficient and secure data sharing scheme forgroups in the cloud is not an easy task due to the followingchallenging issues.First, identity privacy is one of the most significantobstacles for the wide

They addressed the SkNN problem under the following setting: the client has the ciphertexts of all data points in database T and the encryption function of T, whereas the server has the decryption function of T and some auxiliary information regarding each data point. Both methods [51, 98], however, are not secure because they are vulnerable to chosen-plaintext attacks. All the above methods also leak data access patterns to the server. Recently, Yao et al. [99] proposed a new SkNN method based on partition-based a Secure Voronoi Diagram (SVD). Instead of asking the cloud to retrieve the exact kNN, they required the cloud to retrieve a relevant encrypted partitionEpk(G) for Epk(T)such that G is guaranteed to contain the k-nearest neighbors of q. This work, however, solves the SkNN problem accurately by letting the cloud retrieve the exact k-Nearest Neighbors of q (in encrypted form). Additionally, most of the computations during the query processing step in [51, 99, 105] are performed locally by the end-user. That conflicts with the purpose of outsourcing the DataBase Management System (DBMS) functionalities to the cloud. Furthermore, the protocol in secure nearest neighbor revisited[99] leaks data access patterns, such

2. Our proposed plan has the capacity bolster dynamic gatherings productively. In particular, new allowed clients can straightforwardly unscramble information records transferred before their investment without reaching with information proprietors. Client repudiation can be effortlessly accomplished through a novel repudiation list without redesigning the mystery keys of the remaining clients. The size and calculation overhead of encryption are consistent and autonomous with the quantity of repudiated clients.

When I was reading Ona cloud rider I noticed that in one of the scenes they were good clouds and they were bad clouds, both sides different. So I went researching if they were different kinds of clouds. Yes they were different clouds, you can call them rain clouds or you can be more specific and call them high low or medium clouds. The groups are based on the height of the clouds kind of like some MLG tournaments how they referred some of their teams as A, D depending on what position they are in. My 2nd reason why this is real is look at some photographs at clouds, you can see tons of pictures about clouds and they are also some rarities of clouds like uncommon or rare clouds, an example

Data needs to be protected in every form that it holds: stored data, in use data, and mobilized data. Each of these forms have their own distinctive security challenges.

One of the prominent works to accelerate the search over encrypted keywords in the public-key setting is deterministic encryption introduced by Bellare et al. An encryption scheme is deterministic if the encryption algorithm is deterministic. Bellare et al. focus on enabling search over encrypted keywords to be as efficient as the search for unencrypted keywords, such that a ciphertext containing a given keyword can be retrieved in time complexity logarithmic in the total number of all ciphertexts. This is reasonable because the encrypted keywords can form a tree-like structure when stored according to their binary values. Search on encrypted data has been extensively investigated in recent years. From a cryptographic perspective, the existing works fall into two categories, i.e., symmetric searchable encryption and public-key searchable encryption.

The segregation of data is also critical to access controls applied to the data. To insure successful access controls in a cloud environment, with co-located data, the ability to determine who can access the data must reside with the client, in both enterprise and private user applications (Subashini and Kavitha 2011). Security and privacy of cloud-based data is only effective through agreed upon application of policy and governance against the underlying technology architecture.

In asymmetric encryption the public key can be distrusted to anybody while the private key which is kept by an individual. In order for this process to work, it is imperative that the two keys are mathematically paired in order to be able to encrypt and decrypt messages. Because they are mathematically paired, asymmetric encryption can work in both directions, where a message can be encrypted and decrypted with a public or private key, and encrypted and decrypted by the corresponding key. There are several disadvantages to using asymmetric encryption, some of which include that it is slow compared to symmetric encryption and the loss of the private key is an irreversible and unreplaceable action. Despite these disadvantages, the advantages of asymmetric encryption are its convenience in providing a solution for the distribution of the key found in symmetric encryption, and the combination of public and private keys provides us a method of authentication as private keys are needed in order to read the

From the viewpoint of data security, which has always been an important form of quality of service, Cloud computing surely poses new challenging security threats for number of reasons. Firstly, traditional cryptographic primitives for the purpose of data security protection cannot be straight accepted due to users loss control of data under cloud computing. Therefore, verification of correct data storage in the cloud must be attended without accurate knowledge of the whole data. Considering different kind of data for every user stored in the cloud and the requirement of long term continuous security of their data safety, the problem of checking correctness of data storage in the cloud becomes even more challenging.[1]

This project is going to discuss about the Cloud Computing and its application in business. To briefly describe what cloud

In today’s world we are so much dependent on technology, that the need for privacy and data encryption has become more important to protect the importance of information, such as credit-card numbers, email messages, confidential company information, banking details and other personal information. For example, when you are at an Automatic Teller Machine (ATM), you do not want someone looking over your shoulder for your PIN number. The same applies for email accounts, bank accounts, Social-networking accounts. And we do not want an unauthorised person or a third party to monitor our movement over the internet. So as the computer technology and Information technology have evolved, so is the need to secure date increased. Internet usage has increased at an alarming rate, and now every person is using the Internet for various purposes. Researchers have been working hard for a very long time to make Internet and data sharing as safe as possible. They are trying to find new methods of securing and transferring data across the internet and extranet.

The data privacy issue is a main concern in cloud storage system, so the sensitive data is encrypted by the owner before outsourcing onto the cloud, and data users retrieve the interested data by encrypted search scheme. In MCS, the modern mobile devices are encountering with many of the security threats as PCs, and various traditional data encryption methods are imported in MCS [5], [6]. However, mobile cloud storage system incurs new challenges over the traditional encrypted search schemes, in consideration of the limited computing and battery capacities of mobile device, as well as data sharing and accessing approaches through wireless communication. Therefore, a suitable and efficient encrypted search scheme is mandatory for MCS. Generally speaking, the mobile cloud storage is in great need of the bandwidth and energy efficiency for data
